Do you trust your computer?
You shouldn't.

Personal computers are now part of the furniture in homes around the world. We use them for generating, storing and communicating documents and images; we talk to friends and family via email and surf the Web without giving too much thought to the security of our personal information. Unfortunately hacking and computer security are issues which affect all computer users, not just big corporations.

What is a desktop witness?
Your computer stores a record of every document you create, every e-mail you write or receive, which sites you visit on the Internet, even attachments which you don't open.

An unattended computer may reveal your secrets if you leave security vulnerabilities unattended to. It may 'let in' outsiders through your IR port. It 'whispers' behind your back when you are online. Detectable radiation gives away the contents of your screen. Eavesdroppers can hear conversations through your microphone. Your computer remembers everything.

What can you do?
This straight-talking guide, with its easy-to-follow instructions will enable you to regain control and protect your personal information. It will show you the virtues of computer-anonymity, by making you aware of what might motivate people to access your computer in the first place, and it will help you free-up valuable memory by showing you how to really delete the files your computer stores without your knowledge.

A valuable read for any computer user and absolutely essential for any individual, company or practice with information to protect.

Databases are the nerve center of our economy. Every piece of your personal information is stored there-medical records, bank accounts, employment history, pensions, car registrations, even your children's grades and what groceries you buy. Database attacks are potentially crippling-and relentless.

Cyber security is a key issue affecting the confidence of Internet users and the sustainability of businesses. It is also a national issue with regards to economic development and resilience. As a concern, cyber risks are not only in the hands of IT security managers, but of everyone, and non-executive directors and managing directors may be held to account in relation to shareholders, customers, suppliers, employees, banks and public authorities. The implementation of a cybersecurity system, including processes, devices and training, is essential to protect a company against theft of strategic and personal data, sabotage and fraud. Cybersecurity and Decision Makers presents a comprehensive overview of cybercrime and best practice to confidently adapt to the digital world; covering areas such as risk mapping, compliance with the General Data Protection Regulation, cyber culture, ethics and crisis management. It is intended for anyone concerned about the protection of their data, as well as decision makers in any organization.

This book explores the latest developments in fully homomorphic encryption (FHE), an effective means of performing arbitrary operations on encrypted data before storing it in the 'cloud'. The book begins by addressing perennial problems like sorting and searching through FHE data, followed by a detailed discussion of the basic components of any algorithm and adapting them to handle FHE data. In turn, the book focuses on algorithms in both non-recursive and recursive versions and discusses their realizations and challenges while operating in the FHE domain on existing unencrypted processors. It highlights potential complications and proposes solutions for encrypted database design with complex queries, including the basic design details of an encrypted processor architecture to support FHE operations in real-world applications.

The humanities and social sciences are interested in the cybersecurity object since its emergence in the security debates, at the beginning of the 2000s. This scientific production is thus still relatively young, but diversified, mobilizing at the same time political science, international relations, sociology, law, information science, security studies, surveillance studies, strategic studies, polemology. There is, however, no actual cybersecurity studies. After two decades of scientific production on this subject, we thought it essential to take stock of the research methods that could be mobilized, imagined and invented by the researchers. The research methodology on the subject "cybersecurity" has, paradoxically, been the subject of relatively few publications to date. This dimension is essential. It is the initial phase by which any researcher, seasoned or young doctoral student, must pass, to define his subject of study, delimit the contours, ask the research questions, and choose the methods of treatment. It is this methodological dimension that our book proposes to treat. The questions the authors were asked to answer were: how can cybersecurity be defined? What disciplines in the humanities and social sciences are studying, and how, cybersecurity? What is the place of pluralism or interdisciplinarity? How are the research topics chosen, the questions defined? How, concretely, to study cybersecurity: tools, methods, theories, organization of research, research fields, data ...? How are discipline-specific theories useful for understanding and studying cybersecurity? Has cybersecurity had an impact on scientific theories?

This book is an introduction to both offensive and defensive techniques of cyberdeception. Unlike most books on cyberdeception, this book focuses on methods rather than detection. It treats cyberdeception techniques that are current, novel, and practical, and that go well beyond traditional honeypots. It contains features friendly for classroom use: (1) minimal use of programming details and mathematics, (2) modular chapters that can be covered in many orders, (3) exercises with each chapter, and (4) an extensive reference list.Cyberattacks have grown serious enough that understanding and using deception is essential to safe operation in cyberspace. The deception techniques covered are impersonation, delays, fakes, camouflage, false excuses, and social engineering. Special attention is devoted to cyberdeception in industrial control systems and within operating systems. This material is supported by a detailed discussion of how to plan deceptions and calculate their detectability and effectiveness. Some of the chapters provide further technical details of specific deception techniques and their application. Cyberdeception can be conducted ethically and efficiently when necessary by following a few basic principles. This book is intended for advanced undergraduate students and graduate students, as well as computer professionals learning on their own. It will be especially useful for anyone who helps run important and essential computer systems such as critical-infrastructure and military systems.

In today's business environment it is no longer safe to conduct any business on the Internet without first protecting it. Small, medium, and large corporations require a massive dose of security to protect themselves and their digital assets from unwanted intruders. A managerial guide and practical technical tutorial, Securing Windows NT/2000: From Policies to Firewalls provides viable security solutions for your organization.

The author presents in-depth knowledge on how, why, and where these operating systems must be tuned in order to use them securely to connect to the Internet. The book includes the steps required to define a corporate security policy, how to implement that policy, and how to structure the project plan. Tables, charts, and work templates provide a starting point to begin assessing and implementing a solution that will fit the unique needs of your organization.

This Festschrift volume is published in honor of David Kahn and is the outcome of a Fest held in Luxembourg in 2010 on the occasion of David Kahn's 80th birthday. The title of this books leans on the title of a serious history of cryptology named "The Codebreakers", written by David Kahn and published in 1967. This book contains 35 talks dealing with cryptography as a whole. They are organized in topical section named: history; technology - past, present, future; efficient cryptographic implementations; treachery and perfidy; information security; cryptanalysis; side-channel attacks; randomness embedded system security; public-key cryptography; and models and protocols.

In this introductory textbook the author explains the key topics in cryptography. He takes a modern approach, where defining what is meant by "secure" is as important as creating something that achieves that goal, and security definitions are central to the discussion throughout. The author balances a largely non-rigorous style - many proofs are sketched only - with appropriate formality and depth. For example, he uses the terminology of groups and finite fields so that the reader can understand both the latest academic research and "real-world" documents such as application programming interface descriptions and cryptographic standards. The text employs colour to distinguish between public and private information, and all chapters include summaries and suggestions for further reading. This is a suitable textbook for advanced undergraduate and graduate students in computer science, mathematics and engineering, and for self-study by professionals in information security. While the appendix summarizes most of the basic algebra and notation required, it is assumed that the reader has a basic knowledge of discrete mathematics, probability, and elementary calculus.
